In the ""Bank Street Ready-to-Read"" series, Level 2, a ""fact-based"" confrontation with nature, dedicated ""To Fred, who shared the experience,"" that cries out for a bit more information about the events that inspired the intriguing story. A girl and her parents notice peeled, pointed sticks on the dock near their wilderness home. The mystery is soon solved: beavers are building a lodge on this unusual foundation, undeterred by the nearby humans. Mom protests about the many trees that the beavers are cutting; no one likes their strong smell; and there's talk of calling the game warden to move the unwelcome tenants. But then a storm looses the dock and it floats down the river--lodge, beavers, and all. In McCully's appealing pen-and-watercolor illustrations, readers will enjoy spotting the beavers even before the young narrator does. Competently written for the intended level, as well as informative and thought-provoking, but these values are somewhat undermined by the absence of an explanatory note.
